Tantalum Polymer Capacitors – Hermetically Sealed

T550 Axial & T555 Surface Mount 105°C

Overview

The T550 axial leaded and T555 surface mount polymer

hermetically sealed (PHS) devices are tantalum capacitors

with a Ta anode and Ta

dielectric. A conductive organic

polymer replaces the traditionally used MnO

or wet

electrolyte as the cathode plate of the capacitor. This

results in very low ESR and improved capacitance retention

at high frequency and low temperature. The PHS device

also exhibits a benign failure mode, which eliminates the

case breach that can occur in wet tantalum capacitors.

Additionally, this part may be operated at voltages up to

80% of rated voltage, with equivalent or better reliability

than traditional MnO

or wet tantalum capacitors operated

at 50% of rated voltage.

PHS capacitors also offer higher ripple current handling

capability and a lower ESR range than wet tantalums. With

reduced ESR and enhanced capacitance retention at higher

frequencies and low temperatures, these parts provide the

highest total capacitance and the most economical solution

for high power applications, all within an approximately 25%

lighter package than the equivalent wet tantalum capacitor.

Benefits

• Includes F-Tech anode which eliminates hidden defects in

the dielectric

• 100% simulated breakdown screening

• Maximum operating temperature of +105°C

• DLA drawing 13030 qualified parts available

• Polymer cathode technology

• Extremely low ESR

• High frequency and low temperature capacitance retention

• 100% constant voltage conditioning (240 hours)

• 100% surge current tested

• Volumetrically efficient

• Non-ignition failure mode

• Approximately 25% lighter than equivalent wet tantalum

• T555 surface mount design (see dimensions diagram)

Applications

Typical applications include high voltage power management, such as buck/boost converters, filtering, hold-up capacitors,

and other high ripple current applications.
